SSD Tests – IOMeter v2006.07.27 – IOps
Iometer is an I/O subsystem measurement and characterization tool for single and clustered systems. It was originally developed by the Intel Corporation and announced at the Intel Developers Forum (IDF) on February 17, 1998 – since then it got wide spread within the industry.
Meanwhile Intel has discontinued to work on Iometer and it was given to the Open Source Development Lab (OSDL). In November 2001, a project was registered at SourceForge.net and an initial drop was provided. Since the relaunch in February 2003, the project is driven by an international group of individuals who are continuesly improving, porting and extend the product.
Light desktop usage sees QD figures between 1 and 4. Heavy / power user loads run at 8 and higher. Most SSD's are not capable of effectively handling anything higher than QD=32, which explains the plateaus.
Regarding why we use this test as opposed to single-tasker tests like 4KB random reads or 4KB random writes, well, computers are just not single taskers. Writes take place at the same time as reads. We call this mixed-mode testing, and while a given SSD comes with side-of-box specs that boast what it can do while being a uni-tasker, the tests above tend to paint a very different picture.
The Black2 performed very well here, especially in consideration of the SSD part only driving two flash packages. Sure it's not as fire-breathing as SSD-only solutions, but it significantly outperforms WD's own previous SSD model by a large margin.
Wow, I may visit you more
Wow, I may visit you more often. Hope ur still answering fan posts. This is an excellent review, but MORE so the tech discussions which cover the varied setups on laptops (my interest).
REQUEST FOR HELP – Compare Black2 with swapping current 750GB HDD into DVD-based caddy and add internal SSD.
Have Dell N5110, single 750GB HD, Windows 7 Home Premium 64 bit. Even in sleep mode, takes like 3+ minutes to ‘wake up’ and connect to Internet. Restart even worse.
SCENARIOS
1. My present thought “was” get internal SSD, then put 750GB into DVD-based caddy. IT appears 256GB SSD safest in terms of OS “space” route, but then WHICH SSD (reliability, bang for buck)? Also, what caddy will work with my Dell N5110?
If I put the 750GB HDD in a caddy / DVD slot, THEN the POWER is always on, right? Thus the HEAT goes UP in the laptop? Does the Black2 produce MORE heat than the standard HDD?
2. Are YOU using the Black2 hybrid? It is one step easier to use the hybrid (no DVD bay mod), and I get even more storage. As I’ve never had SSD, even the “slower” Black2 write speed will seem like lightning compared to my present startup speed, I think.
Lastly, I’ll note the Dell runs very well as is, ONCE up and running. Thus any purchase is convenience for me, not necessity. I’m often using it for browsing so keep comparing to spending money on a tablet (the new-wave of convenience).
Ok, after reading the full
Ok, after reading the full article, I’d say for my ‘these days’ passive laptop use, often sleep on/off like a tablet… BUT I still want my 750GB (current) storage…
The Black2 looks very attractive, and I’ve used their 5-year warranty long ago with no issues. It’s hard to beat.
Is it possible to multi boot
Is it possible to multi boot os if they are all windows based ie Win 7 8.1 and now Win 10 ?
